red, and have no trace of spots or bands. The specimen is two 

 and a half inches long, and was taken in a river in the northern 

 part of Queensland — probably the Fitzroy. 



Note. — I have seen a specimen of this sort belonging to the 

 Brisbane Museum, six inches long, from the above-named river. 

 I had taken it for fasciatus, but it is certainly distinct, and I 

 believe this latter is confined to the Western Coast of Australia. 



DlACOPUS SUPERBUS. 



The superior profile of this sort is strongly convex, and the body 

 broad ; the height is twice and three quarters in the total length 

 without the caudal fin ; the head is twice and a-half in the same ; 

 the eye is contained four times and one quarter in the length of 

 the head ; at the upper jaw there is in front on each side a very 

 large canine, and on the lower one six or seven of different sizes ; 

 the notch of the prseopercule is very distinct, and receives a 

 slight knob of the interopercules ; below this notch are several 

 arched spines directed forward ; the operculum ends in a point ; 

 the body scales are large. 



The first dorsal has ten strong spines, of which the 4th is the 

 longest ; caudal truncate ; anal with three spines and eight rays, 

 the 1st spine is straight and short ; the 2nd, very large, arched and 

 thick ; the 3rd, very little longer than the second, rather arched 

 and slender ; the 2nd, 3rd, and 4th rays are the longest ; pectorals 

 of seventeen rays ; the ventrals are far from reaching the base 

 of the anal. 



This beautiful fish is brown on the back, with the centre of 

 each scale obscure ; the lower parts are of a handsome pink 

 colour ; dorsal, caudal and anal of a brilliant scarlet. Pectorals 

 and ventrals pink. 



My specimen is twenty inches long, but it is said to attain a 

 larger size. 



This fish inhabits Moreton Bay, and is called at Brisbane,. 

 Red Bass ; it is said to be a v«ry good table fish.
